In humans skin color widely varies. This is because skin color is?
Answer:
Human skin color ranges in variety from the darkest brown to the lightest hues. An individual's skin pigmentation is the result of genetics, being the product of both of the individual's biological parents ' genetic makeup, and exposure to sun.
Explanation:
YOU ARE WELCOME!!!!:)
In humans, skin color widely varies because it is a polygenic trait. It is influenced by two or more different genes.
What are polygenic traits?A polygenic trait is a characteristic or trait such as height or skin color or pigmentation, which is influenced by two or more genes. Because, multiple genes are involved in this trait, a polygenic trait do not follow the patterns of Mendelian inheritance. Many polygenic traits are also influenced by environment and are called multifactorial traits.
The pigment melanin is produced by melanocytes, is primarily responsible for the skin coloration of an individual. Melanin pigment comes in different shades of brown and black color. Individuals with darker skin color have darker, more abundant melanin, whereas the fair-skinned individuals have a lighter shade of skin pigmentation and less melanin.

5. If you were given an unfamiliar vegetable, how could you tell if it was a root or a stem, based on its external features and a microscopic examination of its cross section
Answer:
In roots, the vascular tissues, i.e., xylem and phloem, are found in the central vascular cylinder, while in stems these tissues are dispersed throughout the stem, generally arranged as a ring towards the outside of the stem (epidermis)
Explanation:
Vascular plants have two different transport tissues: xylem and phloem. The xylem transports water from roots to stems and leaves, while the phloem transports food (i.e. dissolved sugars) from the leaves to all parts of the plant. In roots, vascular tissues form a central core in order to withstand stretching forces. Moreover, in stems, vascular tissues are dispersed (generally concentrated towards the epidermis), in an arrangement that enables them to resist compression and bending forces.
Which equation best represents the aerobic respiration reaction?
The chemical equation which best represent an aerobic respiration reaction is: D. Glucose + Oxygen -----> Carbon Dioxide + Water + ATP.
An aerobic reaction can be defined as both biological and chemical processes that generally takes place in the presence of oxygen.
This ultimately implies that, an aerobic reaction requires oxygen before it can occur.
On a related note, an aerobic respiration reaction refers to how the body of a living organism uses oxygen such as;
Running. Swimming. Walking. Jogging.Basically, the two main reactants (inputs) reactants for an aerobic respiration reaction include:
Glucose.Oxygen.Conversely, the end products of an aerobic respiration reaction are:
Carbon dioxide.Water.ATP.In conclusion, the chemical equation which best represent an aerobic respiration reaction is:
[tex]Glucose + Oxygen ---> Carbon \;Dioxide + Water + ATP[/tex]

The equation that best represents the aerobic respiration reaction is: Glucose+ oxygen→ Carbon Dioxide+ Water+ ATP.
In this equation, glucose (C6H12O6) is oxidized in the presence of oxygen (O2) to produce carbon dioxide (CO2), water (H2O), and energy. This is the process of aerobic respiration, which occurs in the mitochondria of cells to generate energy for cellular activities.
Vigorous breath is the organic cycle where food glucose is changed over into energy within the sight of oxygen. The majority of mammals, birds, humans, and plants use this kind of respiration.

What is the name of the winds that blow from the Poles southward?
Trade Winds
Westerlies
Sub-Arctic Northerlies
Polar Easterlies
Trade Winds is the name of the winds that blow from the Poles southward. So, the correct option is (A).
What are Winds?Wind is the movement of air caused by the uneven heating of the Earth by the Sun and the rotation of the Earth. This includes natural calamities/disasters ranging from light breeze to storms and tornadoes.
Sometimes winds arise from differences in atmospheric pressure. At the equator, the sun heats the water and land more than the rest of the world. Warm equatorial air rises up in the atmosphere and migrates towards the poles. This type of system is called a low pressure system while at the same time, cooler, denser air moves over Earth's surface toward the equator to replace the warmer air. This type of system is called a high pressure system.
The boundary between these two areas is called a front and the complex relationships between fronts cause different types of wind and weather patterns. The Earth contains five major wind zones:

Modern birds and lizards share a common ancestor that was an ectotherm.
Which of the following explains the fact that lizards are also ectotherms but
birds evolved to become endotherms?
A. The difference is due to the fact that birds are more highly
evolved.
B. A recent random mutation could account for the change in birds.
C. A split occurred sometime in the past in response to different
environmental pressures.
D. Birds acquired the endothermy trait so they could improve their
own chances of survival.
Answer: c
Explanation:
The fact that lizards are also ectotherms but birds evolved to become endotherms because a split occurred sometime in the past in response to different environmental pressures. Option C is correct.
Ectotherms are organisms that rely on external sources of heat to maintain their body temperature. Endotherms are organisms that generate their own heat internally. Birds and lizards share a common ancestor that was an ectotherm. This means that at some point in the past, there was a split in the lineage that led to birds and lizards, and one lineage evolved endothermy while the other lineage remained ectothermic.
There are a number of possible explanations for why this split occurred. One possibility is that the environment that the two lineages were living in changed, and one lineage was better suited to the new environment than the other. For example, if the environment became colder, the lineage that evolved endothermy would have been better able to maintain its body temperature and survive. Option C is correct.

Which of these changes produces a chemical change?
O A. A stone fizzes and forms a gas when acid is dropped on it.
B. Limestone slowly dissolves in water and forms a cave.
O C. Lava cools and changes from a thick fluid to solid rock.
OD. A large rock is crushed into gravel.
Answer:
Explanation:
Limestone (CaCO3) dissolves in water - with difficulty - but remains, and can be recovered as CaCO3
Solidifying lava and rock crushed to gravel are physical changes.
If acid dropped on a rock causes fizzing and gives of gas, that is a chemical reaction, e.g,
CaCO3 + 2HCl —> CaCl2 + H2O + CO2
Dissolution of limestone in water does result in dissociation into ions that may be hydrated, but CaCO3 is precipitated out as solutions become more concentrated.
CaCO3 + 2H2O —> Ca++ + CO3= + OH- + H3O+

Which of these is true about energy?
Can be destroyed
Cannot be created
Cannot be transformed
Can be increased in a closed system.
The statement "Cannot be created" is true about energy.
According to the law of conservation of energy, energy cannot be created or destroyed in an isolated system. This principle is known as the conservation of energy or the first law of thermodynamics. Energy can only be transformed from one form to another or transferred between different objects or systems.
Energy exists in various forms such as kinetic energy (associated with motion), potential energy (stored energy), thermal energy (heat), chemical energy (stored in chemical bonds), electrical energy, and so on. These different forms of energy can be converted from one to another through processes like mechanical work, heat transfer, chemical reactions, and electrical currents.
While energy can be transformed and transferred, the total amount of energy within a closed system remains constant. In other words, the total energy before and after any energy transformation or transfer remains the same.
However, it is important to note that energy can be lost or dissipated in the form of heat or other forms of energy that are not easily usable or recoverable. This loss of usable energy can lead to a decrease in the overall energy available to do work within a system.
In summary, the statement "Cannot be created" is true about energy, as energy is conserved and cannot be created or destroyed in an isolated system. It can only be transformed from one form to another or transferred between objects or systems.
